been working with someone to produce some custom electronics to suit my needs, here are the results.
measures the temps of all modules and the base plate and displays the results on an illuminated LCD. then when a set temp is reached by the base plate sensor it activates fans within the projector

Nice!
I also did something similar while back
turns out my programming skills was hopeless
Its basically just a thermometer, couldn't figure out the IF/OR value to control the relay
Maybe someone could help me out on that :)

Would love to but I've not got a clue sorry
Andy,
Can you tell us a little more on how they attach and if your selling them currently or when they might be available?
This is a really great idea.
Cheers, Ian
all you have to do is drill a 4mm round hole in the base plate of the module and insert the sensor, same with the projector base plate.
add 5v to the board and job done
um not sure yet, not sure there is enough interest.
is the fan control PID controlled or does it just look for a set temperature?
Um not sure off the top of my head would need to find out.
The board uses a relay and is triggers on a set temperature. It currently toggles every 10 seconds to avoid rapid on/off pulses in case the temperature is right on the edge.
Hmmm, that's pretty crude!
Simple proportional control using the micros PWM ( for variable speed fan ) would be light years better than a relay!

just spoke to the chap he is going to alter slightly
Wohoooo!
Got my coding right! :D
PWM controlled fan instead of an relay :D

Cheers!
looks great good work
Cheers mate!
Was about to give up this morning, because few month back I had no luck,
your thread kickstarted my mind again :P
can anyone think of any other useful features a board like this could contain?
Current draw for each individual diode/TEC.
Maybe a little splash screen on boot? Hehe
Hour meter for each module & total system run time?
Also resettable system run time to help with monitoring maintainance intervals?
Safety interlock status maybe to help with fault finding?
I'm sure we can think of plenty more useful/flashy things it could show and do;)
Yup!, just like WookieBoy said,
I would love to give it a try and program it to have hour meter, interlock, safety shutter linked to it, its possible to use a full colour lcd touch screen like the ones on the phone and use a Arduino Mega to do all those things, probly wifi to see all the status on your pc or iphone would be cool, but for now im limited to my programming skills :P
Raspberry PI should be very cool too!
Ok hour meters done for next Version

Dan
any good laser module e.g. green should heat and cool.
sadly all Chinese stuff cools only

That was attached to a 12 watt RRGB OPS Laser, no gayness there... Well, other than my complete love for that system and its three brothers :D
lol your so gay mark!
